“…This is, after all, the main objective of the study. For estimation purpose, we use seemingly unrelated regression method with random effects in the context of panel data as suggested by Biørn (2004).…”

“…However, the econometric methods available for the estimation of a system of equations for unbalanced panel-data are relatively new. Biørn (2004) develops a procedure for the estimation of a one-way Seemingly Unrelated Regression (SUR) system with random effects (RE). Monte Carlo simulations show that SUR techniques are superior as compared to the standard single equation FE and RE estimators.…”

“…Monte Carlo simulations show that SUR techniques are superior as compared to the standard single equation FE and RE estimators. Therefore, we estimate equations (6) and (7) simultaneously using SUR with one-way random effects (RE) as suggested by Biørn (2004). We prefer RE to FE with selection determined by Hausman (1978).…”

“…For example, it is possible to control firm-level heterogeneity in order to avoid biased estimates. Furthermore, due to time and cross-firm dimensions, there is more information, less collinearity and greater efficiency in the estimates (Biørn, 2004;Baltagi, 2005).…”

“…We further tested for heteroskedasticity using White's test (White 1980), and for autocorrelation using the Durbin-Watson test (Greene 2002), and did not find any problems. As there are multiple projects per PM, the SUR estimation for panel data uses random effects to correct for any potential correlation of residuals across projects that are nested within the PM (Greene 2002, Biørn 2004). In our SUR estimation, we added the dummy variable dVendorClient, indicating the vendor's prior client experience, to the client satisfaction equation, to render the parameters in the two equations different and identify the system of equations (Wooldridge 2002).…”

For more information on INFORMS, its publications, membership, or meetings visit http://www.informs.org T his study examines the role of project managers' (PM) practical intelligence (PI) in the performance of software offshore outsourcing projects. Based on the extant literature, we conceptualize PI for PMs as their capability to resolve project related work problems, given their long-range and short-range goals; PI is targeted at resolving unexpected and difficult situations, which often cannot be resolved using established processes and frameworks. We then draw on the information processing literature to argue that software offshore outsourcing projects are prone to severe information constraints that lead to unforeseen critical incidents that must be resolved adequately for the projects to succeed. We posit that PMs can use PI to effectively address and resolve such incidents, and therefore the level of PMs' PI positively affects project performance. We further theorize that project complexity and familiarity contribute to its information constraints and the likelihood of critical incidents in a project, thereby moderating the relationship between PMs' PI and project performance. Information Systems ResearchTo evaluate our hypotheses, we analyze longitudinal data collected in an in-depth field study of a leading software vendor organization in India. Our data include project and personnel level archival data on 530 projects completed by 209 PMs. We employ the critical incidents methodology to assess the PI of the PMs who led these projects. Our findings indicate that PMs' PI has a significant and positive impact on project performance. Further, projects with higher complexity or lower familiarity benefit even more from PMs' PI. Our study extends the literatures on project management and outsourcing by conceptualizing and measuring PMs' PI, by theorizing its relationship with project performance, and by positing how that relationship is moderated by project complexity and familiarity. Our study provides unique empir...

Unleashing the indirect influence of oil prices on food prices via exchange rate: New evidence from Pakistan

Oil prices not only affect the agricultural commodity directly but also indirectly through different channels. However, among these channels, the most important is the channel of exchange rate. The reason for putting emphasis on the mediating role of exchange rate between the oil prices and food prices nexus is that the oilimporting counties like Pakistan pay their import bills in terms of foreign currency in the international market which as a result escalates the demand for foreign currency in oil-importing countries. This study has analyzed the indirect influence of oil prices on food prices via exchange rate. We developed a Composite Index (CI) of the agricultural commodity prices including wheat, cotton, rice, gram, sugar cane, and maize. This index is generated by using Principal Component Analysis (PCA). Further, to construct our econometric model, we used mediation approach by applying Seemingly Unrelated Regression (SUR) model. The results indicate a positive relationship between exchange rate and prices of oil. We also found the same relationship between exchange rate and the food prices. In addition to this, we witnessed positive effects of prices of oil on the food prices in the presence of exchange rate. Our study confirms that exchange rate partially mediates between the nexus of oil prices and food prices. Our analysis explains the impact of oil price on agricultural commodity prices through the channel of exchange rate by using time series data of Pakistan.
